I'm sorry, but I'm not an expert on mp3 tags and editing them.
I find that I can't select the field "Title" in the Actions menu but instead have to use the Edit Metafields button to get access to this field, contrary to some topic instructions.
My question is this:
How do I change the contents of this field from
00\_Genesis
T0
00 Genesis?
I went and read the topic regular expressions but I don't get it. Some web sites on the topic are even harder to understand.
This seems relatively easy to do for fields available under the Actions menu field selection drop down menu. However the only field with Title in the name is Titlesort.
Thanks for your help in advance.
Tony

If there is no TITLE item just type it in.
Or click on the little triangle button on the right and choose "Reset fields..."

Ok. I reset the fields. The TITLE field showed up.
Now how do I remove the first 3 characters of each value in TITLE and append the track number with a space between the last character of title and the track number?
Example:
01\_1st\_Corinthians TO 1st\_Corinthians 01
Thanks

_Action type:_ **Format value**
_Field:_ **TITLE**
_Format string:_ **$cutleft(%title%,3) $left(%title%,2)**
or
_Action type:_ **Replace with regular expression**
_Field:_ **TITLE**
_Regular expression:_ **^(\d\d)\_(.+)$**
_Replace matches with:_ **$2 $1**

For example:
Begin Action Group **Test 2010#20101219.TonyFree**
Action #1
_Actiontype 5:_ **Format value**
_Field:_ **TITLE**
_Formatstring:_ **$cutLeft(%TITLE%,3)÷$left(%TITLE%,2)**
_Note: Replace each special ÷ character with one space character._
End Action Group **Test 2010#20101219.TonyFree** (1 Action)
